TS Rust

TS Rust is a direct Rust port of Microsoft's native TypeScript compiler that provides high-performance type checking.

ts-rust is a direct port of Microsoft's native TypeScript compiler written in Rust. It functions as a drop-in replacement for tsc with the same command line, language server, and API. The tool includes built-in Effect language service diagnostics so projects do not need a secondary compiler. It is designed for developers seeking fast type checking and supports running within WebAssembly. Standalone archives are available alongside the npm package tsc-rs.
